The Globally Trapped Future: A Fate for Black Holes and Wormholes
Yi-bo Liang, Hong-Rong Li
We demonstrate, for the first time, that arbitrary spherically symmetric metrics can be derived within a framework based on the coupling of two scalar fields and an electromagnetic…

Sharp mean-field analysis of permutation mixtures and permutation-invariant decisions
Yiguo Liang, Yanjun Han
We develop sharp bounds on the statistical distance between high-dimensional permutation mixtures and their i.i.d. counterparts. Our approach establishes a new geometric link betwe…

Regular Power-Maxwell Black Holes
Yi-bo Liang, Hong-Rong Li
We present a new class of regular, spherically symmetric spacetimes in nonlinear electrodynamics that are asymptotically dynamical but not de Sitter, exhibiting power-law Maxwell b…
